Specification of Letters Patent.

n atented April 9, 1907.

Application filed May 4, 1906. Serial. No. 315,212.

To all whom, it may concern:

Be it known that l, ROBERT EDWIN REAR- Dpiy, a citizen of the Dominionof Canada, residing in tne city of Ottawa, in the county of Carleton,Province of Ontario, Canada, have invented lmprovements in Sights forFirearms; and l do hereby declare the following to be a full, clear, andexact description of the same.

My invention relates to improvements in rifle-sights, and moreparticularly to mechanism by which a very fine adjustment of the variousgages may be had. 4

My invention relates also to the sightingaperture which gives a cleardeiinition and perfect alinement of the fore-sight.

Another feature is that my new sight may be applied to a great majorityof the sightleaves now in use without alterations to the same.

My invention consists, broadly, in a bar to be applied to the leaf orstandard of various types of rilie-sights, and it comprises,

l first, a wind-gage having an adjusting device consisting of a screwhaving a head so shaped that upon the turning of the same an adjustmentequal to degrees or fraction of degrees may be indicated by the sense oftouch second, a vertical adjustment of the eyepiece, also by means of ascrew having the same features as that of the wind-gage, the range ofadjustment being made to extend to a maximum of one hundred yards ormore above or below the point to which it has been set 5 third, asighting -piece carrying two sighting-apertures so positioned that oneof the apertures may he used when the sight is in either the vertical orhorizontal position 3 fourth, a sighting'- aperture of a U or V shapedform, centrally positioned on the diameter or chord of a half-circle orsegment.

The invention comprises also certain other features of construction andarrangement of parts, that will be hereinafter described and claimed.

ln the drawings, Figure 1 is a rear view of the sight as turned up, theleaf being shown in section only. Fig. 2 represents a rear view of thecomplete sighting-bar as it appears when the leaf is in a horizontalposition. Fig. 3 represents a side view of the sighting-b ar on the sidewhere the adjustingscrews are mounted. Fig. 4' represents a face andedge view of a part of the sight-leaf. Fig. 5 represents a face view ofthe sightingbar with the sighting-piece removed. Fig.

same along the line b b, Fig. 5.

6 represents a transverse section view ofthe sents a face view of theeyepiece-carrier with the eyepiece removed. Fig. 8 is a top view ofthesame. Fig. 9 represents a rear view of the eyepiece. Fig. 10 representsa front view of the same. Fig. 11 represents a modiiication` of thesightingaperture.- Fig. 12 represents a modification of the adjustingdevice of the sighting-bar. Fig.- 13 represents a modiiication for Vtherapid adjustment of the eyepiece when using the wind-gage. Fig. 14represents a section of the vertical adjusting-screw along the line a a,Fig. 3.

The device is composed of three main parts, which will be designatedthroughout this speciication as, rst, the sighting-bar, (de- Fig. 7repre-v noted by the letter A;) second, the eyepieeecarrier, (denoted bythe letter 13;) third, the eyepiece, (denoted by the letter O.)

The sighting-bar (illustrated by Figs. 5 and 6) is preferably cut outfrom a single piece of metal. 1 is the central slot for the rifle-leaf.The walls 2 2 of the slot 1 are centrally notched, as at 3. This notchis intended to give clearance to the sighting-aperture. The end 4 of thenotch 1 is shaped as shown. lt is slotted lengthwise, as shown at Fig. 6by 5, and endwise, as shown in dotted lines, Fig. 5. These slots serveas a recess for the friction-piece 6, Fig. 6. The shape of that piece 6is shown in Fig. 12. The notches 7 7 are the means to retain the same inthe recess 5 when pins 8 8 are in position. A spring 9 keeps the piece 6in frictional contact with the riiie-leaf 10and to iin the sighting-baron the rifle-leaf a thumbscrew 11 is threaded through the end 4, asshown. lts inner end presses against the center of spring 9 and tightensthe frictionpiece 6 against the rifle-leaf 10.

Fig. 12 shows a modified form of the device previously described. Thismodification aflords a means by which the sighting-bar may be adjustedto one hundred yards, or thereabout, by the sense of touch. The screw 11is centrally perforated. A pin 12 passes through the same. This pin hasan enlargement 13 resting against the spring 9. lt will be seen that thepin 12 passes through the friction-piece 6 and engages the rifle-leaf 10by means of small indentations 13 on said leaf. The pin 12 has a freemovement in the screw 1 1 and friction-piece 6. The part of the pinengaging the indentation is rounded off, and, the indentations being`shallow, it will be TOO evident that'if the `linger be applied on theend of the screw 11 and the sighting-bar made to slide up or down theleaf 1() every time the pin 11 coincides with an indentation it willfall therein, causing a depression of said pin sufficient to be felt bythe finger.

Referring again to Fig. 5, the right end 14 of the sighting-bar notch 1is shaped as Shown. lt is provided with a slot 15, shaped as shown'in'Fig. 6. A screw 16 extends the whole length of the slot and is 'fixedas to its longitudinal movement in the end piece 14 by means of a pin 17engaging a circular groove 18, which groove is integral with the screw16. The screw 16 is hereinafter called the "vertical adjusting-screw Thehead of this screw is triangular in cross-Sectiemfi. e., an equilateraltriangle with the corners rounded off, as shown by Fig. 14. This shapewill enable the fingers to detect each face of the screw-head when thesame is being rotated. It will be evident, therefore, that if onecomplete turn of the screw causes a nut engaging the same to be movedone degree three faces of the screw-head will have been presented to thefinger, while if one-third degree adjustment is required one face onlywill have been presented.

Referring now to Figs. 7 and S, representing what has been hereinbeforecalled the eyepiece-carrier7J B, 19 is a notch corresponding to thenotch 3 and intended also to clear the sighting-aperture of theeyepiece. 20 is a 'nut made integral with the eyepiececarrier andintended to engage the adjustingscrew 16 of the sighting-bar. 21 is atongue made to slidably engage the groove S4 of the sighting bar. Thiseyepiece carrier when connected to the sighting-bar by the two partsabove mentioned will on the turning of the screw 16 cause the piece B tomove up or down the sighting-bar, the movements corresponding to thedirection the screw 16 is being turned. The piece B has a longitudinalgroove 22 and a perforation 23, (shown in dotted lines,) adapted toreceive the adjustingscrew 24. The head of this screw is shaped. asshown in Fig. 3 1'. e., an equilateral triangle with the head roundedoff. This shape serves the same purpose as explained heretofore withregard to the screw 16. The piece B has a projection 26 standing atright angles to the face of the piece B and is shaped ,to protect thehead of the screw 24.

Referring now to Figs. 9 and 10, representing the eyepiece C, 26 is theeye-aperture, made U-shaped in this case and positioned, as heretoforeexplained, underneath the diameter or chord of a half-circle or sector.27 is the eye-aperture used when the sight is in a horizont-al position.This aperture is positioned at right angles with regard to aperture 26.35 is a nut made to engage groove 22 of the eyepiece-carrier and tothread on the screw 24 of the same piece. It will be evident, therefore,that since the thread of screw 24 is cut so that one turn represents onedegree of adjustment the eyepiece C will be moved exactly as previouslyexplained with regard to the adjusting-screw 16. This screw 24 is thewind-gage screw.

Fig. 13 represents an attachment that may be used in connection with theadjustment of the wind-gage. This figure is a section crosswise on c c,Fig. 9. 28 is a button carrying a stem29, having an elongatedperforation 30, said perforation being threaded at its lower end. Thethreads correspond to that on screw 24. A` short lug 31 terminates thestem. .L1-spring 32 keeps the threaded part of the perforation 30 intoengagement with the screw 24. This button is placed in a recess 33practiced in the eyepiece C. T he operation of this device is asfollows: When the button is depressed, the thread on the stem disengagesthe screw 24, and the eyepiece may then be moved freely from right toleft, or vice versa, on the eyepiece-carrier; but whenever in thesemovements the eye-aperture passes centrally of the sight the lug 31 onthe end of the stem will drop in a perforation 36 on theeyepiece-carrier, thereby indicating the central position of theeye-aperture.

The operation of my device is as follows: The rifle-leaf having beenraised in the vertical position, the sighting-bar is adjusted toapproximately the range required by releasing the friction-piece 6 fromthe friction-leaf, which is done by unscrewing the said screw Y1.1, bysliding the bar to the graduation indieating the range sought, andrescrewing the said screw 11 tight and the friction-piece 6. Should itthen be :found that the range is short, the adjusting-screw 16 may beturned from right to left, when the linger will detect the degrees orfraction of a degree every time one of the surfaces of the screw-headcomes forward. lt will be understood that the reverse action of thisscrew will shorten the range. Should it now be found that the winddeflects the projectile, the wind-gage screw 24 may be brought intoaction, and as the head of this screw is also provided with a pluralityof surfaces the degrees or fraction of a degree may be counted by thesensation on the fingers as each face is presented.

T lay great stress on this perception by the sense of feeling of theminute variations invariably required to be corrected in accuratesighting. This is a great advantage, as the eye need not leave theshooting-point when making corrections in the sighting. This feature isalso desirable when shooting` in dark or noisy surroundings.

I am aware that attempts have been made to adjust rifle-sights by thesense of hearing g but one has only to take into consideration the noiseoccasioned by the reports of firearms to disregard this means.
